'headers already sent' error after upgrading

Hi Happyches,

Thanks for the message, but this problem is not caused by this plugin, I upgraded my wordpress tooltips plugin to 3.2.3 on my site from https://www.ads-software.com/plugins/wordpress-tooltips/ too, and the upgrade is success, there are no any error notification,
you can find my plugins works well at https://tomas.zhu.bz/wordpress-plugin-tooltips.html/, maybe you need check the setting of your ftp software or if you changed code in our plugin, please be careful UTF-8 format, I guess mabye you changed some language for your users in your country, if so you need be careful your UTF-8 format, thanks.

Best Regards,
Tomas

Also the line 12 is “<?php”

You can find the line 12 is “<?php”, so there are no any code problem, please check what you changed in our plugin and your UTF-8 setting, Especially if you customized our plugin.

Hiya Tomas,

I upgraded it the normal way (didn’t do it via FTP)..

I just went to Dashboard > Updates
Put a check in the checkbox next to Tooltips, and clicked Upgrade

I didn’t need to change any language either (my blog is English)

But not sure what you mean here.. :
“please be careful UTF-8 format”

Do I have to change something in regards to this? Where/why/how? ??

Kind Regards,

Penny

If I “disable” tooltips, then “delete” tooltips..
Will I lose all my tooltips, or are they safe in the database?

Then I can do a clean install of it, and see if that fixes the problem?

(although I just checked the svn and it looks the same (at a glance) so I dont think anything got corrupted while upgrading)

https://plugins.svn.www.ads-software.com/wordpress-tooltips/trunk/tooltips.php

So weird if it’s only happening to me..

I can’t download an older version.. in developers.. all the svn versions are empty.. when you download the zip, the zip is empty and the svn’s are empty.. any chance of getting hold of the previous version? (version 3.2.1)

Fixed it.. don’t know why it’s fixed, maybe a character or something in your code?

But I deleted this bit of code (compared the new file to my older version backup on a different server that I found).. and everything works perfect now.

Had to remove all of this: (suspect it’s just a space or something that would’ve done the trick, but I don’t know where to look so just tested this and it worked).. hope that helps you find the character that might of caused it…

Had the same problem, thanks Happyches for solving it.

WordPress 3.8 english, updated plugin via dashboard – did not made any modifications at all before in it.

Had the same problem everytime I tried to add category or write something. I had to remove all this code:

So something’s wrong in it. Tomas.Zhu did you tried to add anything on your page? I can see that there are no new posts or anything so try adding new post or new category and you should encounter the same problem i think.

PS. This plugin is great! ??

@happyches, Hey, thanks for fix the problem! It is a strange error, In my hosting after upgrade it works well, I tried to searched the google and wordpress support forum, I do found some brother said blank line maybe will caused some problem in some hosting?

The reason of the blank line problem is because from this version I followed wordpress suggestion to add license information(https://codex.www.ads-software.com/Writing_a_Plugin#License), I fully copy the wordpress license texts, so I guess this part texts should have no problem and the problem is caused the blank line.

I had rewrite a new version of tooltips plugin, in which I remove the blank line which after “?>” and before “<?php”, also I added a new line “error_reporting(0);” to avoid problem, hope this works well on your hosting, if any problem more, please tell me, I will try to find the rease, thanks.

About old version 3.2.1, when I hope to upload it in tags->3.2.1 in svn, wordpress svn hosting always failed, I tried many times, but it always stoped the process when I upload jquert.js, I will try to upload old version again some days later.

@berek333, Thanks for the message, I have no this kind of problem on my hosting, I upgrade the tooltips plugin via wordpress back end too, I guess maybe some hosting have blank line problem? I had published a new version to try to solve this problem.

About “did you tried to add anything on your page”
Sorry, I am not sure I understand which page you mentioned?

About “PS. This plugin is great! :)”
Hey! Thanks, I am try to make it more easy to use and have more features! ??

Best Regards,
Tomas
